7892a1f64a [media] rcar-fcp: Make sure rcar_fcp_enable() returns 0 on success
When resuming from suspend-to-RAM on r8a7795/salvator-x:

    dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
    PM: Device fe940000.fdp1 failed to resume noirq: error 1
    dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
    PM: Device fe944000.fdp1 failed to resume noirq: error 1
    dpm_run_callback(): pm_genpd_resume_noirq+0x0/0x90 returns 1
    PM: Device fe948000.fdp1 failed to resume noirq: error 1

According to its documentation, rcar_fcp_enable() returns 0 on success
or a negative error code if an error occurs.  Hence
fdp1_pm_runtime_resume() and vsp1_pm_runtime_resume() forward its return
value to their callers.

However, rcar_fcp_enable() forwards the return value of
pm_runtime_get_sync(), which can actually be 1 on success, leading to
the resume failure above.

To fix this, consider only negative values returned by
pm_runtime_get_sync() to be failures.

91ae0e1ec6 [media] vcodec:mediatek: Fix visible_height larger than coded_height issue in s_fmt_out
The original code add extra 32 line to visible_height.
It is incorrect, 32 line should be add to coded_height.
The purpose is that user space could calcuate real buffer size needed by using
coded_width * coded_height.
But this method will make v4l2-compliance test fail, since g_fmt != s_fmt(g_fmt)
So remove extend visible_height or coded_height, user space should just
use sizeimage to get real buffer size needed

The cec_get_edid_spa_location() function did not verify that the IEEE
identifier in the Vendor Specific Data Block matched the HDMI-LLC
identifier. This could result in the wrong VSDB block being returned.

For example, for HDMI 2.0 EDIDs there is also a HDMI Forum VSDB.

So check the IEEE identifier as well.

bb9bd87808 drivers/media/dvb-frontends/cxd2841er.c: avoid misleading gcc warning
The addition of jump label support in dynamic_debug caused an unexpected
warning in exactly one file in the kernel:

  drivers/media/dvb-frontends/cxd2841er.c: In function 'cxd2841er_tune_tc':
  include/linux/dynamic_debug.h:134:3: error: 'carrier_offset' may be used uninitialized in this function [-Werror=maybe-uninitialized]
     __dynamic_dev_dbg(&descriptor, dev, fmt, \
     ^~~~~~~~~~~~~~~~~
  drivers/media/dvb-frontends/cxd2841er.c:3177:11: note: 'carrier_offset' was declared here
    int ret, carrier_offset;
             ^~~~~~~~~~~~~~

The problem seems to be that the compiler gets confused by the extra
conditionals in static_branch_unlikely, to the point where it can no
longer keep track of which branches have already been taken, and it
doesn't realize that this variable is now always initialized when it
gets used.

I have done lots of randconfig kernel builds and could not find any
other file with this behavior, so I assume it's a rare enough glitch
that we don't need to change the jump label support but instead just
work around the warning in the driver.

To achieve that, I'm moving the check for the return value into the
switch() statement, which is an obvious transformation, but is enough to
un-confuse the compiler here.  The resulting code is not as nice to
read, but at least we retain the behavior of warning if it gets changed
to actually access an uninitialized carrier offset value in the future.

00085f1efa dma-mapping: use unsigned long for dma_attrs
The dma-mapping core and the implementations do not change the DMA
attributes passed by pointer.  Thus the pointer can point to const data.
However the attributes do not have to be a bitfield.  Instead unsigned
long will do fine:

1. This is just simpler.  Both in terms of reading the code and setting
   attributes.  Instead of initializing local attributes on the stack
   and passing pointer to it to dma_set_attr(), just set the bits.

2. It brings safeness and checking for const correctness because the
   attributes are passed by value.

Merge tag 'media/v4.8-4' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media documentation updates from Mauro Carvalho Chehab:
 "This patch series does the conversion of all media documentation stuff
  to Restrutured Text markup format and add them to the
  Documentation/index.rst file.

  The media documentation was grouped into 4 books:

    - media uAPI
    - media kAPI
    - V4L driver-specific documentation
    - DVB driver-specific documentation

  It also contains several documentation improvements and one fixup
  patch for a core issue with cropcap.

  PS.  After this patch series, the media DocBook is deprecated and
  should be removed.  I'll add such patch on a future pull request"

4360fa22ad drivers: misc: ti-st: Use int instead of fuzzy char for callback status
On mips and parisc:

    drivers/bluetooth/btwilink.c: In function 'ti_st_open':
    drivers/bluetooth/btwilink.c:174:21: warning: overflow in implicit constant conversion [-Woverflow]
       hst->reg_status = -EINPROGRESS;

    drivers/nfc/nfcwilink.c: In function 'nfcwilink_open':
    drivers/nfc/nfcwilink.c:396:31: warning: overflow in implicit constant conversion [-Woverflow]
      drv->st_register_cb_status = -EINPROGRESS;

There are actually two issues:
  1. Whether "char" is signed or unsigned depends on the architecture.
     As the completion callback data is used to pass a (negative) error
     code, it should always be signed.
  2. EINPROGRESS is 150 on mips, 245 on parisc.
     Hence -EINPROGRESS doesn't fit in a signed 8-bit number.

Change the callback status from "char" to "int" to fix these.

d2f019851a [media] doc-rst: Fix conversion for dvb-core.rst
The conversion from DocBook required some fixes:

- Now, the C files with the exported symbols also need to be
  added. So, all headers need to be included twice: one to
  get the structs/enums/.. and another one for the functions;

- Notes should use the ReST tag, as kernel-doc doesn't
  recognizes it anymore;

- Identation needs to be fixed, as ReST uses it to identify
  when a format "tag" ends.

- Fix the cross-references at the media controller description.

313a7dfb23 [media] cxd2841er: fix signal strength scale for ISDB-T
The scale for ISDB-T was wrong too: it was inverted, and
on a relative scale.

Use a linear interpolation to make it look better.
The formula was empirically determined, using 3 frequencies
(175 MHz, 410 MHz and 800 MHz), measuring from -50dBm to
-12dBm in steps of 0.5dB.

d12b791e3d [media] cxd2841er: adjust the dB scale for DVB-C
Instead of using a relative frequency range, calibrate it to
show the results in dB. The callibration was done getting
samples with a signal generated from -50dBm to -12dBm,
incremented in steps of 0.5 dB, using 3 frequencies:
175 MHz, 410 MHz and 800 MHz. The modulated signal was
using QAM64, and it was used a linear interpolation of all
the results.

988bd281d3 [media] cxd2841er: provide signal strength for DVB-C
Currently, there's no stats for DVB-C. Let's at least return
signal strength. The scale is different than on DVB-T, so let's
use a relative scale, for now.

4216be14be [media] cxd2841er: fix BER report via DVBv5 stats API
What userspace expects is to receive both bit_error and bit_count
counters. So, instead of doing the division at the Kernel,
return the counters for userspace to handle it the way it
wants.

aa93d1fee8 media: fix airspy usb probe error path
Fix a memory leak on probe error of the airspy usb device driver.

The problem is triggered when more than 64 usb devices register with
v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV.

The memory leak is caused by the probe function of the airspy driver
mishandeling errors and not freeing the corresponding control structures
when an error occours registering the device to v4l2 core.

A badusb device can emulate 64 of these devices, and then through
continual emulated connect/disconnect of the 65th device, cause the
kernel to run out of RAM and crash the kernel, thus causing a local DOS
vulnerability.

Fixes CVE-2016-5400

eca2d34b9d [media] mb86a20s: apply mask to val after checking for read failure
Appling the mask 0x0f to the immediate return of the call to
mb86a20s_readreg will always result in a positive value, meaning that the
check of ret < 0 will never work.  Instead, check for a -ve return value
first, and then mask val with 0x0f.

Kudos to Mauro Carvalho Chehab for spotting the mistake in my original fix.

785ef73dba [media] airspy: fix error logic during device register
This patch addresses CVE-2016-5400, a local DOS vulnerability caused by
a memory leak in the airspy usb device driver.

The vulnerability is triggered when more than 64 usb devices register
with v4l2 of type VFL_TYPE_SDR or VFL_TYPE_SUBDEV.A badusb device can
emulate 64 of these devices then through continual emulated
connect/disconnect of the 65th device, cause the kernel to run out of
RAM and crash the kernel.

The vulnerability exists in kernel versions from 3.17 to current 4.7.

The memory leak is caused by the probe function of the airspy driver
mishandeling errors and not freeing the corresponding control structures
when an error occours registering the device to v4l2 core.

8d4eb2acb6 [media] mtk-vcodec: fix default OUTPUT buffer size
When calculate OUTPUT buffer size in vidioc_try_fmt, it will
add more size hw need in each plane.
But in mtk_vcodec_enc_set_default_params, it do not add
same size in each plane.
This makes v4l2-compliance test fail.
This patch fix the issue.

19e476c7b0 [media] mtk-vcodec: fix more type mismatches
The newly added mtk-vcodec driver produces a number of warnings in an
ARM allmodconfig build, mainly since it assumes that dma_addr_t is
32-bit wide:

mtk-vcodec/venc/venc_vp8_if.c: In function 'vp8_enc_alloc_work_buf':
mtk-vcodec/venc/venc_vp8_if.c:212:191: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]
mtk-vcodec/venc/venc_h264_if.c: In function 'h264_enc_alloc_work_buf':
mtk-vcodec/venc/venc_h264_if.c:297:190: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast]

This rearranges the format strings and type casts to what they should
have been in order to avoid the warnings. e0f80d8d62 ("[media]
mtk-vcodec: fix two compiler warnings") fixed some of the problems that
were introduced at the same time, but missed two others.
